By arranging at least two such bending spring elements parallel next to each other becomes high Tilt stability also achieved perpendicular to the ring planes. Total results good tilt stability of the spring device in all Directions. Due to the parallel arrangement of the spiral spring elements is also an unproblematic one-piece production guaranteed.
  • the spiral spring elements preferably have a cross-section in the ring plane Elongated shape. This will ensure the tipping stability advantageously increased in the ring plane.
  • the spiral spring elements are also preferably at a distance from one another on and are over in their upper and / or lower ring section an at least approximately perpendicular to the spring direction Connection section connected to each other. This will ensure the tipping stability advantageously increased transversely to the ring planes.

  • the two outermost spiral spring elements can be one below the other have the same height, which is greater than the height at least an inner spiral spring element.
  • the spring device When applying a force the spring device will initially only be the two outermost spiral spring elements loaded and compressed so that only their spring properties determine the spring characteristic of the spring device. Only after The inner spiral spring element also covers a certain spring travel loaded with lower height and bears with its spring properties to determine the spring characteristic of the spring device. Due to the external arrangement of the spiral spring elements with larger The good tilt stability remains high even with this multi-stage spring device preserved in all directions. If there are more than three next to each other arranged spiral spring elements can also further spiral spring elements have the same height as the two outermost spiral spring elements. It is important to have a symmetrical arrangement in order to get the good one Maintain tilt stability.
  • a spring device with at least three a multi-stage spring characteristic curve arranged next to each other to realize consists of a spring arrangement with a such spring device and support means for supporting the spring device to provide, in which the two outermost spiral spring elements and at least one inner spiral spring element is identical to one another Have height and with a compression of the spring device with each a support means cooperate, the support means of the two outermost spiral spring elements with each other simultaneously and in front of the support means come into effect for the inner spiral spring element.
  • the two outer spiral spring elements can for example on one Support surface to be supported, in the area of the central spiral spring element has a recess so that it is initially unsupported is.
  • the spring characteristic of the spring device is initially only by the two extreme bending spring elements determined and only after replacement a certain travel through the two outermost and the middle Bending spring elements together. Because the two are extreme Spiral spring elements are supported in front of the central spiral spring element, is again good tilt stability perpendicular to the ring planes guaranteed.
  • a spring device with at least two essentially annular spiral spring elements, whose ring planes run in the spring direction, to be provided at which at least partially nested the spiral spring elements in such a way are arranged that when a compression force is introduced an outer spiral spring element in each case after covering a first spring travel comes to rest on a next inner spiral spring element and part of the compression force during a second spring travel transfers to this.
  • spiral spring elements By nesting such spiral spring elements can be a multilevel spring characteristic in a structurally uncomplicated manner can be achieved.
  • Two, three or more spiral spring elements can be used arranged side by side in an outer spiral spring element be, or the spiral spring elements can be nested multiple times his.

  • the ring planes of the spiral spring elements are at least partially perpendicular to each other. This ensures a high level of stability in all ring levels and thus overall good tipping stability achieved in all directions.
  • the different Levels of the spring characteristic are set to different body weights. This has the advantage that the spring device provides support for People with different weights can be built. At People with a lower weight essentially only work the first Level of the spring characteristic, which is effective by the one or the first Bending spring elements is determined. For people with a larger body weight come the other spiral spring element or elements Effect, so that the at least co-determined by this spring characteristic comes into play.
  • the spiral spring elements preferably have a round one Shape, especially the shape of an ellipse or oval, the major axis is transverse to the direction of the spring. This can have a good spring effect be achieved. This form is also aesthetically special appealing. Another advantage of such a form is that the spring elements increasingly compress to one for support Put on the used cover plate and a base plate. The one at the respective Spring plate adjacent sections of the spiral spring elements no more, so that ever shorter sections of the spiral spring elements Determine the spring characteristic. This results in a particularly advantageous manner Way a continuously progressive spring characteristic.
  • the spiral spring elements have the shape of a polygon, which in particular transversely to the spring direction has a greater extent than in the spring direction.
  • the spiral spring elements can have the shape of a have elongated hexagons with parallel long sides, whose major axis is transverse to the direction of the spring. The bending points are therefore relatively far out in the short sides of the hexagon, so the tilt stability can be further improved.
  • the long sides the hexagon lie on the top and base plates and contribute practically nothing to the elasticity of the spiral spring elements.
  • the four short sides of the hexagon can face outwards or inwards point. However, it is particularly favorable for the bending properties when the four short sides face out.
  • the spiral spring elements preferably have the shape of a flat band on, the flat sides of which run transversely to the direction of the spring. So that becomes a high stability combined with good spring properties.
  • the spiral spring elements can also only have a cover plate and / or be connected to each other via a base plate.
  • the connecting sections between the spiral spring elements are unnecessary, and material is saved accordingly.
  • At least one part the spiral spring elements releasably with a cover plate and / or Base plate connectable.
  • a spring device with three the central spiral spring element arranged next to each other either used to change the spring characteristic or be omitted.
  • an exchange for other spiral spring elements is easily possible in this way.
  • the spiral spring elements can also be composed of partially ring-shaped elements his.

  • the two partial ring elements can also remain spaced from each other, that is, shortened accordingly his.
  • the ring is then over the connecting section or sections the cover and / or base plate closed. This can also cause material be saved.
  • the spring device shown in Fig. 1 to Fig. 4 comprises two side by side arranged spiral spring elements 1, 2, each in the form of a have an elliptical ring, as can be seen in particular in FIG. 2.
  • the Both spiral spring elements 1, 2 also have a flat, ribbon-like Form on, the flat side is transverse to the spring direction I.

  • the support surface 5 can be used directly as a support surface, serve for example for a cushion element or a mattress.
  • Corresponding can the support surface 6 directly to support the spring device serve on a pad. But it is also possible in the area the support surfaces 5 and 6 connecting means for a separate cover plate or to provide a base plate.
  • the tilting stability of the spring device is due to the transverse to the spring axis I elongated shape of the two spiral spring elements 1, 2 in Direction of the ring planes of the two spiral spring elements 1, 2 particularly high. Transversely to this is also a high stability against tipping, since the two spiral spring elements 1, 2 are spaced apart. All in all This results in good tilt stability of the shown in all directions and described spring device.
  • Another improvement in spring properties and tilt stability can be achieved in that the material thickness of the two spiral spring elements 1, 2 in the areas running approximately in the spring direction 7 is reduced. These properties can also be improved be that the width of the two spiral spring elements 1, 2 in this Areas 7 is reduced. Both lead to the fact that the necessary Bending force reduced to achieve a certain travel. This also increases the stability of the device.
  • the variant of a spring device according to the invention shown in FIGS. 5 and 6 is similar to the variant shown in FIGS. 1 to 4.
  • the spiral spring elements 1, 2 not the shape of an elliptical ring, but the shape of an oval Ring on.
  • the elongated shape transverse to the spring direction I is, however also present here, so that the tilt stability in the ring planes in particular good is.
  • the tilting stability is also good across the ring planes, because also in this variant two spiral spring elements 1, 2 next to each other at a distance are arranged. This also results in good tipping stability in all directions.
  • connection section 3 Another difference from the first variant is that the two mutually spaced spiral spring elements 1, 2 only in one upper ring section integrally with one another via a connecting section 3 are connected, while in the lower ring sections Connection section is provided. Because of the distance between the two spiral spring elements 1, 2 is the support of the spring device still good on a pad. The same applies if instead of the Connection section 3 only one connection section 4 in the lower Ring sections of the two spiral spring elements 1,2 is provided.
  • FIG. 7 and 8 show a variant of the spring device according to the invention, in which a third spiral spring element 8 is arranged between the two spiral spring elements 1, 2.

Besides, it is possible, instead of the upper long sides 9, 10 of the three spiral spring elements 1, 2 and 8 to form their lower longitudinal sides 9, 10 in one piece with one another, by connecting them flush.
  • the narrow sides 11, 12 of the spiral spring elements 1, 2 and 8 with respect to the respective ring surface is not angled outwards, but angled inwards his. With a corresponding extension of the long sides 9, 10 maintain good tilting stability in all directions.
  • FIG. 9 Another possibility is a spring device with a two-stage spring characteristic to realize is shown in Fig. 9. Again, there are three spiral spring elements 1, 2 and 8 in the form of an elongated, hexagonal Ring arranged side by side and with a parallel ring plane. However, the central spiral spring element 8 has the same dimensions here on how the two outer spiral spring elements 1, 2. The two-stage Spring characteristic is now realized in that the spiral spring elements 1, 2 and 8 interact with different support means.
  • the spring device shown Since the two outer spiral spring elements 1, 2 a large distance from each other have, the spring device shown also has vertical to the ring levels a high tilt stability. Because the two outside Bending spring elements 1, 2 are also effective during the second spring travel remain, the high stability against tipping remains during the second travel receive. Overall, therefore, this spring device also has a high tilt stability in all directions.
